Yes — Strong Match
silver lace vine (zones 4-8) covers every zone Maryland contains (5b-8a), so hardiness is not what limits it anywhere in the state.
Your yard isn't the whole zone.
Maryland spans zones 5b-8a, but your yard sits in exactly one — and slope, tree cover, and cold-air pockets nudge it further. Enter your address and we'll score silver lace vine against your parcel's actual hardiness, soil, and sun.

When to Plant Silver Lace Vine in Maryland
The frost window
Across Maryland, the last spring hard freeze (28°F) clears between Mar 18 and Mar 29, and the first fall hard freeze lands between Nov 11 and Nov 27 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 227-day window you can count on — up to 254 days on a mild site in a kind year. That marks the hard freeze, not the last light frost, so tender transplants usually wait another 2-3 weeks.
Winter standing
Maryland runs as cold as USDA zone 5, and no sourced winter-hardiness floor is on record for silver lace vine, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether silver lace vine is a permanent planting or a replant-every-spring crop for you turns on your own zone within Maryland; check its hardiness range against that before treating it as long-lived ground.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: USDA PLANTS Database. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.
Growing Season Fit
The zone check says silver lace vine survives winter here. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Silver Lace Vine wants 120+ frost-free days; a typical Maryland site sees ~238 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
Growing degree days
Silver Lace Vine needs ~1500 GDD (base 50°F) to ripen. The state median runs ~3789 GDD (from PRISM 1991-2020 climate normals), so Maryland's typical season clears that easily.
GDD and chill-hour figures are computed from PRISM 1991-2020 monthly climate normals; frost-free days from NOAA Regional Climate Centers ACIS, 1991-2020. Each is the state median across its counties (P25/P75 span the within-state spread). Hardiness-zone range is USDA PHZM 2023.
Soil + Drainage Fit
Silver Lace Vine likes near-neutral soil (pH 5.5-7.5). That's the common-ground band across Maryland's silt loam and clay — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 6 and 7 — worth knowing before you decide whether a Maryland soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Maryland site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

What Else to Consider for Silver Lace Vine in Maryland
Zone compatibility tells you about winter cold survival — but Maryland growers also need to think about:
Heavy Piedmont clay drains poorly
Humidity and heat in summer promote disease
Deer pressure in suburban areas is extreme
What to actually do about these — and the constraints that apply to every Maryland grower, not just silver lace vine — is covered on the Maryland growing guide.
Timing shifts within Maryland
Silver Lace Vine needs about 120 days of frost-free season to complete its cycle. Even Garrett County — Maryland’s shortest season at 190 frost-free days — clears that by 70 days, so season length isn’t the constraint anywhere in Maryland. What varies is your own parcel.
Across Maryland’s 24 counties the frost-free season runs from 190 days in Garrett County to 270 days in Talbot County — a spread of 80 days, which is why a single statewide planting date misleads. The median Maryland county sees 238 frost-free days, leaving silver lace vine about 118 days of slack on a typical parcel — room for a second sowing where the season runs long.
County last-freeze dates and frost-free day counts: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). Silver Lace Vine's 120-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Where in Maryland Fits Best
Even within Maryland's zones 5b-8a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for silver lace vine (USDA PHZM 2023):
Pollinator + Wildlife Value
Silver Lace Vine draws honeybees and native bees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, silver lace vine can only work that bloom inside Maryland's frost window — roughly 238 days, opening after the last 28°F freeze (Mar 18 - Mar 29) and closing at the first (Nov 11 - Nov 27), per NOAA Regional Climate Centers ACIS, 1991-2020.
Maryland Cooperative Extension
For Maryland-specific cultivar recommendations, planting calendars, and pest pressure for silver lace vine, the canonical source is University of Maryland Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Silver Lace Vine native to Maryland?
No — the USDA PLANTS Database lists Silver Lace Vine as introduced rather than native in the Lower 48, so it is not part of Maryland's native flora. It grows here as a garden plant; pairing it with a few Maryland natives keeps local pollinators fed too.

Common Questions About Growing Silver Lace Vine in Maryland
When can I plant Silver Lace Vine in Maryland?
Maryland's last spring hard freeze (28°F) clears between Mar 18 and Mar 29, and the first fall hard freeze lands between Nov 11 and Nov 27 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Silver Lace Vine, so this page does not state whether it overwinters in Maryland and publishes no fall establishment date for it — check its hardiness range against your own zone before treating it as a permanent planting.
What hardiness zone is Silver Lace Vine grown in across Maryland?
Maryland spans USDA hardiness zones 5b-8a (USDA ARS PHZM 2023). Silver Lace Vine carries a range of zones 4-8, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Maryland site have?
A typical Maryland site sees ~238 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Silver Lace Vine needs 120+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Silver Lace Vine native to Maryland?
No — the USDA PLANTS Database lists Silver Lace Vine as introduced rather than native in the Lower 48, so it is not part of Maryland's native flora. It grows here as a garden plant; pairing it with a few Maryland natives keeps local pollinators fed too.
How should I amend the soil for Silver Lace Vine in Maryland?
Silver Lace Vine prefers pH 5.5-7.5 and well (dry spells) drainage (Growable Ground Plant Database). That sits in the common-ground band across Maryland soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will Silver Lace Vine actually grow on my specific land in Maryland?
